do you want validator on your asp.net page to validate that user does not enteres " and ' in any specific field?

If you wrote some simple regex before, you should be able to do this with a little effort. However, if you have limited background regarding the subject matter, I suggest you go through the links first.

Reference

Regex with Javascript

Test your regex with this tool

You can also use the FilteredTextBoxEntender from the AjaxControlToolkit.
Then set following properties of the FilteredTextBoxExtender
FilterMode = Custom<br />
FilterType = InvalidChars<br />
InvalidChars = '" 
(without commas else comma will also be considered invalid.)

The following code can be used to disallow " and ' in TextBox
ASP
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<asp:RegularExpressionValidator ID="RegularExpressionValidator1" runat="server"
    ControlToValidate="TextBox1" ErrorMessage=" and ' are not permitted"
    ValidationExpression="[^"']*"></asp:RegularExpressionValidator>
